Hi Everyone,

I need to protect the backside of a flexible circuit where the copper is
exposed through the Polyimide through our cupric etcher.  The opening is to
deep for dry film and if I use liquid resist that thick I cannot get it to
strip.

Does anyone know of a "peel able" etch resist that might work for this
application?

Suppliers or vendors are welcome to contact me directly

Thanks in advance,

Chuck Brummer
